What Are Anthocyanins And Why Are Purple Foods So Healthy?

Examples of antioxidants include vitamins C and E, selenium, and carotenoids, such as beta-carotene, lycopene, lutein, and zeaxanthin. This fact sheet provides basic information about antioxidants, summarizes what the science says about antioxidants and health, and suggests sources for additional information. Evidence from many epidemiological studies suggests that high intakes of fruits and vegetables are associated with a reduced risk of cardiovascular disease . This association might be partly attributable to the antioxidant content of these foods because oxidative damage, including oxidative modification of low-density lipoproteins, is a major cause of cardiovascular disease . Even though supplements did not prove beneficial in avoiding heart problems, foods that are sources of antioxidants are still recommended. There are benefits to getting vitamins in food that don’t necessarily occur in supplement form.

• The implications of these analyses for the potential adverse effects of high-dose vitamin E supplements are unclear [56-59].
• Antioxidants protect the body from oxidative damage induced by free radicals and reactive oxygen species by suppressing their formation; acting as scavengers; and acting as their substrate.
• Anthocyanins are a class of pigments that occur naturally in plants.
• Antioxidants are incredibly important, but most people don’t really understand what they are.
• Protecting the kidneys is crucial, for once they are damaged, it becomes hard, if not impossible, to restore healthy function.
• Dietary antioxidants protect circulating cholesterol from oxidation, so it is not absorbed by scavenger cells .
• She’s also the author of The Plant-Powered Diet, the editor of Environmental Nutrition, and a contributing editor to Today’s Dietitian.
• The AREDS2 study, which also tested formulations containing 500 mg vitamin C, confirmed these findings .
• Most of our top 10 are healthy foods that also have hidden benefits.
• Green tea has flavonoids and catechins, which can help prevent cell damage and may help improve brain function, Ansari says.
• For example, some day health practitioners may be able to determine whether a particular patient has the ability to convert isothiocyanates from broccoli into cancer-preventing compounds.
• Herbal/traditional plant medicine is the most antioxidant-rich category in the present study and also the category with the largest variation between products (Table 2.2).
• The truth is that camu camu definitely does deserve superfood status because not only is its ORAC near the top of the chart, but in particular it is the #1 highest source of vitamin C.
• Cacao provides many other health benefits as well, including stress reduction, reduced blood pressure, brain health, and more.

In the second study, men and women had a 13- to 15-percent increase in the antioxidant power of their blood after doubling their daily fruit and vegetable intake compared to what they consumed before the study. Just doubling intake, without regard to ORAC scores of the fruits and vegetables, more than doubled the number of ORAC units the volunteers consumed, said Prior. Other than for dietary antioxidant vitamins – vitamin A, vitamin C and vitamin E – no food compounds have been proved with antioxidant efficacy in vivo. Antioxidants are our first line of defence against free radical damage and extremely important for maintaining a healthy body. Within our body, many processes occur all the times and for these our body need oxygen.

Unfortunately, human trials and surveys that have attempted to associate vitamin E intake with cancer incidence have found that vitamin E is not beneficial in most cases.

We need oxygen to live, but byproducts resulting from the body’s oxidizing processes, called free radicals, can damage our cells, causing aging, tissue damage and inflammation. These dangerous agents are called free radicals because they are molecules with an unpaired electron looking to bond with another electron in your body. Free radicals in your cells are the result of stress , pesticides and other chemicals in the environment, including cigarette smoke and burnt foods.

However, it is important to ensure the chocolate you consume is 70% cocoa or higher. The presence of excessive milk in chocolate can prevent the full absorption of anti-oxidants into the body. Increasing age is the dominating factor for the onset of cataracts and AMD because of physiological and biochemical changes due to old age.
